◆ build_assign() [5/6]

gassign * build_assign ( enum tree_code code,
tree op1,
int val,
tree lhs )
Build a new gimple assignment.  The LHS of the assignment is a new
temporary whose type matches the given expression.  MODE indicates
whether the LHS should be an SSA or a normal temporary.  CODE is
the expression code for the RHS.  OP1 is the first operand and VAL
is an integer value to be used as the second operand.

◆ build_assign() [6/6]

gassign * build_assign ( enum tree_code code,
tree op1,
tree op2,
tree lhs )
Build and return a new GIMPLE assignment.  The new assignment will
have the opcode CODE and operands OP1 and OP2.  The type of the
expression on the RHS is inferred to be the type of OP1.

The LHS of the statement will be an SSA name or a GIMPLE temporary
in normal form depending on the type of builder invoking this
function.

◆ build_type_cast() [1/2]

gassign * build_type_cast ( tree to_type,
gimple * op,
tree lhs )

◆ build_type_cast() [2/2]

gassign * build_type_cast ( tree to_type,
tree op,
tree lhs )
Create and return a type cast assignment. This creates a NOP_EXPR
that converts OP to TO_TYPE.

Return the expression type to use based on the CODE and type of
the given operand OP.  If the expression CODE is a comparison,
the returned type is boolean_type_node.  Otherwise, it returns
the type of OP.
